PURPOSE: To prevent danger of discharging raw gas from combustion parts by providing in parallel a plurality of combustion parts in a gas stove or the like, and an erroneous operation preventive mechanism in a combustion controller for controlling the feed of a gas to the combustion parts and igniting the combustion parts in a predetermined fire transfer order.

CONSTITUTION: In the main body of the burner inclined cam parts 11 corresponding to push operating members 6 of valves 4 of combustion parts at positions where fire transfer is impossible unless is made through the preceding combustion parts are provided at positions acting on the push operation at the rear half of the push operating members 6. A stopper 13 movable against the force exerted by a return spring 12 is provided at the side body of each inclined cam part 11. Consequently, a movable plate 9 constituting an erroneous operation is moved against the force exerted by a return spring 8 initially by the pushing operation of the rear half push operating members 6. In the vicinity of the termination of the pushing operation of the push operating members 6, the operation of valves 4 interposed between gas passages 17b and 17c connected to the combustion parts at positions where fire transfer is impossible unless it is made through the preceding combustion parts is enabled. Thereby, the simultaneous operation of the push operating members 6 can be preventsd.
